Airborne dust in mine which is produced during reshuffling of the ore exposes workers to the risk of pneumoconiosis as it provides the opportunity for coal dust to explosion and spread. This article describes air-and-water spraying systems which are used in long wall shearers, road headers, conveyor transfer points and roadways. The clear and lightweight design of roadway spraying systems means that wherever dust exists in the air the solutions can be used. The spraying systems form an integral part of longwall shearers and their purpose is to reduce levels of airborne dust and to prevent explosion of methane. Using air and water spraying systems will minimize concentration of dust by up to 80 per cent and lead to a substantial reduction in air dust concentration. Some test results regarding the effectiveness of air-and-water spraying systems, verification tests of the author's spraying solutions are provided there's even talk about nozzles.
